(I) working condition of water taking operation:
when laboratory workers prepare to take water, firstly, the water taking depth is determined, the hydraulic telescopic rod (3) is started, the hydraulic telescopic rod (3) slowly extends out, the cable synchronous motor (15) operates to gradually release the integrated cable (14) on the cable drum (17), meanwhile, the water pipe synchronous motor (6) operates to gradually release the water taking pipe (8) on the water pipe drum (5), and the integrated cable (14) and the water taking pipe (8) synchronously extend into seawater (12) along with the hydraulic telescopic rod (3) until the water taking depth position is reached;
the hydraulic telescopic rod (3) stops running, signals are sent to the cable synchronous motor (15) and the water pipe synchronous motor (6), and the cable synchronous motor (15) and the water pipe synchronous motor (6) stop running;
the submersible pump (10) starts to operate, and seawater (12) at a specified depth is pumped to a laboratory through the water intake pipe (8);
(II) recovering the working condition:
after laboratory workers get water at the target depth, a retraction instruction is sent to the hydraulic telescopic rod (3); the hydraulic telescopic rods (3) are gradually and sequentially retracted, the cable synchronous motor (15) operates to gradually retract the integrated cable (14) in the water, meanwhile, the water pipe synchronous motor (6) operates to gradually retract the water taking pipe (8) in the water, and the integrated cable (14) and the water taking pipe (8) are synchronously retracted along with the hydraulic telescopic rods (3) until the retraction working condition is completed;
(III) adjusting the target depth, and continuously taking water:
when laboratory workers need to change the water taking depth after taking water from a certain depth, the extension or retraction of the hydraulic telescopic rod (3) is controlled according to the comparison between the target depth and the depth of the submersible pump (10), and when the hydraulic telescopic rod (3) extends, the action is consistent with the working condition of the water taking operation until the preset depth is reached; when the hydraulic telescopic rod (3) is retracted, the action of the device is consistent with the working condition of the retraction of the device (II) until the preset depth is reached.
